Abstract (en)
The present application refers to a filter cartridge assembly comprising a filter cartridge defining a filter chamber; a pleated filter assembly secured in the filter chamber having alternating folds including an inner set of folds and an outer set of folds, wherein the pleated filter assembly has a top end and a bottom end, wherein the distance between the two ends defines the axial length of the pleated filter assembly, wherein the filter assembly has a longitudinal axis, and wherein each fold defines a substantially linear apex substantially parallel with the longitudinal axis; a filter core having a core wall that defines an outlet, wherein the filter core is secured in the filter cartridge cage surrounded by the pleated filter assembly, wherein the apexes of the inner set of folds register against the core wall, wherein the core wall defines a plurality of through-bores each having a cross-sectional diameter; and, characterized by a core wrap superposed about the filter core, wherein the wrap comprises spaced webbing segments, wherein for any given through-bore, at least one webbing segment at least partially traverses the given through-bore to provide structural support to the pleated filter media without substantially compromising flow dynamics, and wherein at least some portions of the spaced webbing segments partially occlude the plurality of through-bores to reduce the functional cross-sectional diameters or lengths of the plurality of through-bores.
